Adaptive Headlights in the BMW 3 Series Touring.
A winding road at night. The optional Bi-Xenon headlights move in harmony with the bend ahead: the beams of the 3 Series' headlights stay on the road. Sensors in the Touring monitor the rate of yaw, the steering angle and the vehicle's speed. The result: outstanding illumination and a more relaxed driving experience. (standard only on the 335i)
